Replacement battery for the Bob pen. Bob charger has a universal 510 thread and plugs into any USB port for quick and easy charging of your Bob Pen battery or another device.
Comes with a sleek, slim battery and USB charger.
Instructions for use:
Thread battery onto USB charger and plug into a USB port to charge.
When light on USB charger turns green, remove battery from charger and thread on a 510 thread cartridge.
Place the tip of the cartridge to your lips and draw air through it three times. This ensures Bob oil will coat the ceramic coils inside. Not doing this prior to use will heat the coils dry and will result in a metallic taste.
